re PR lto/59468 (ICE on invalid C++ code with LTO in gimple_get_virt_method_for_binfo, at gimple-fold.c:3224)
PR lto/59468
* ipa-utils.h (possible_polymorphic_call_targets): Update prototype
and wrapper.
* ipa-devirt.c: Include demangle.h
(odr_violation_reported): New static variable.
(add_type_duplicate): Update odr_violations.
(maybe_record_node): Add completep parameter; update it.
(record_target_from_binfo): Add COMPLETEP parameter;
update it as needed.
(possible_polymorphic_call_targets_1): Likewise.
(struct polymorphic_call_target_d): Add nonconstruction_targets;
rename FINAL to COMPLETE.
(record_targets_from_bases): Sanity check we found the binfo;
fix COMPLETEP updating.
(possible_polymorphic_call_targets): Add NONCONSTRUTION_TARGETSP
parameter, fix computing of COMPLETEP.
(dump_possible_polymorphic_call_targets): Imrove readability of dump; at
LTO time do demangling.
(ipa_devirt): Use nonconstruction_targets; Improve dumps.
* gimple-fold.c (gimple_get_virt_method_for_vtable): Add can_refer
parameter.
(gimple_get_virt_method_for_binfo): Likewise.
* gimple-fold.h (gimple_get_virt_method_for_binfo,
gimple_get_virt_method_for_vtable): Update prototypes.
PR lto/59468
* g++.dg/ipa/devirt-27.C: New testcase.
